This circuit was taken from a remote control tarantula transmitter operating at 49. 86MHz. The schematic can also be found at the FCC web site, if you look up the FCC ID. This operates under Part 15. 235 of the FCC rules and regulations Do you need help with.... -
This SMD FM transmitter has an operating frequency of about 80 to 115MHz. Under reasonable circumstances you will be able to receive its signal at a distance of about 200 meters. Although it is low-power, it might be illegal in your part of the planet..... -
FM and AM transmitter in one small device built of cd4001 integrated circuit. It broadcasts on 20MHz(AM) and 100Mhz(FM).... -
This small transmitter uses a hartley type oscillator. Normally the capacitor in the tank circuit would connect at the base of the transistor, but at VHF the base emitter capacitance of the transistor acts as a short circuit, so in effect, it still is. The.... -
Information about building a small radio transmitter, which has a PCB 1. 75" x 2. 5" (45mm x 68 mm) and has a range of about 30 yards or so. The documentation with the circuit says the freq range is 100-108 MHz, but I have found it to be more like 85-100.... -
The Muntz one-tube design can be considerably improved by adding an audio preamplifier stage. This will give improved sensitivity, and thus give full modulation with lower-level signal sources (such as some older CD players, ceramic phono cartridge, etc. )..... -
Crystal X1 is fundamental mode, calibrated for parallel resonance with a 32 pF load. The final output frequency is generated by frequency multiplication within the MC2833 IC. The RF output Buffer (Pin 14) and Q2 Transistor are used as a frequency tripler and.... -
Hi Expert, I recently receive some question on an oscillator in some AM transmitter. I searched the web and find this circuit. According to author,.... -

@ goldsmith If you need a complete circuit , i have thousands of these circuits in my designs . i can give you some of them easily , but you have told .... -
As with your square wave, you will interfere with people`s radios, & they will become quite upset, plus you may attract the attention of the licencing authority-& believe me, you don`t want that! you need I believe a colpits oscilator, this will have a "tank.... -
Tuned circuits consist of C4, L1, C8, L3, and the two 15 pF trimmer capacitors across the collectors and emitters of both transistors. Other NPN transistors like BC54, 2N3642, 43, etc should also work. The circuit is designed for simplicity, so No Audio .... -
The circuit was designed to produce a 500mW output power transmitter whose signal modulated by FM using four transistors. Transmitter an electronic devi.... -
The circuit was designed to operate a frequency modulation voice transmitter over the FM band 2 frequency range of VHF. Transmitter an electronic device.... -
This FM transmitter circuit is very simple and it has a acceptable transmission . The signal transited from this FM transmitter circuit can be received at.... -
You ll find that this is a very easy project to build. It will transmit good quality sound in the FM band ( 88 108 mhz ). One inportant item is that the.... -

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
